The title Schiff base compound, C(23)H(30)N(2)O(2), has crystallographic twofold rotation symmetry. An intra-molecular O-H⋯N hydrogen bond forms a six-membered ring, producing an S(6) ring motif. The imino group is coplanar with the benzene ring. The two benzene rings are almost perpendicular to each other, making a dihedral angle of 87.38 (4)°. In the crystal structure, neighbouring mol-ecules are linked along the c axis by weak inter-molecular C-H⋯O hydrogen bonds and are further packed into columns along the b axis, forming sheets which are parallel to the bc plane.
